This patch is looking pretty good to me, modulo the failing pg_dump
Attached is a fixup patch. I have mainly updated some comments and
variable naming for (my) clarity. No functional changes.
Committed all that.
Testing now this patch is in, I'm unable to create a subscription:
bench=# CREATE PUBLICATION pgbench
FOR TABLE pgbench_accounts , pgbench_branches,
WITH (PUBLISH INSERT, PUBLISH UPDATE, PUBLISH DELETE);
bench=# CREATE SUBSCRIPTION pgbench
CONNECTION 'port=5447 user=postgres dbname=bench'
WITH (COPY DATA);
ERROR: duplicate key value violates unique constraint
DETAIL: Key (srrelid, srsubid)=(0, 16389) already exists.
This is a pair of freshly initdb'ed instances, the master has a size 100
I'm guessing this is a different bug from the segfault also reported
Yes, I also forgot to check if the table actually exists on subscriber
when fetching them in CREATE SUBSCRIPTION (we have check during
replication but not there).
Attached patches should fix both issues.
Yep, does seem to.
I note that (probably intensional) specifying 'COPY DATA' does not
'CREATE TABLES' for you...ok, I probably didn't read ...something
somewhere...but anyway, after creating the tables it all seems to work.
However one minor observation - as Michael Banck noted - the elapsed
time for slave to catch up after running:
$ pgbench -c8 -T600 bench
on the master was (subjectively) much longer than for physical streaming
replication. Is this expected?
